US Building Footprints

In 2019, Microsoft released a dataset containing over 125 million computer generated building footprints for the United States. It was released under the Open Data Commons Open Database Licence (ODbL), which means that users are free to share, modify and use the data in a variety of ways, including commercial use.

It’s a fantastic resource but the geojson files tend to load quite slowly in QGIS. Therefore, we’ve converted each state dataset to the GeoPackage file format, as well as attaching to each feature a FIPS code indicating the state or county a building is in. We’ve also added the county name and a GEOID field to each feature, to allow for easier filtering. You can download the data below by clicking on individual state names. We hope you find this useful.
